MX400 Pro & Motor Mount question

[dkmillerii]

I just bought a HeliMax MX400 Pro from Tower Hobbies.

I have 2 problems.

1. The screws to mount the stabilizer supports to the tailboom are supposed to be machine screws. They sent screws for plastic.

2. The motor came w/ 2 different size sets of screws. All 4 screws fit in the corresponding holes in the motor, but the smaller screws are almost impossible to screw in and the bigger screws don't fit in the holes in the motor mount.

I'm going to drill the motor mount so that the larger screws fit, but has anyone else had these problems?

Thanks,
Don

Yes, I've had both of those problems with an MX450. I had to replace the stab mount anyway, and I had to drill out the motor mount too. Make sure you slot it where it's supposed to be slotted so you can adjust the backlash.
